A small, ornamental grass native to the wet, rocky cliffs of Japan's Honshu Island, including the area around Mount Hakone, after which the species is named. It is a slow spreading, semi-evergreen grass which builds into gently cascading hummocks of bright green that are useful as a simple understorey to light shrubs and as a soft edging to paths or steps. Fine, light sprays of lime green flowers appear during June and July, giving a billowing lightness to planted drifts. The clean, minimalist style of this grass makes it a good choice for formal courtyards or in minimalist urban planters and the fresh green foliage gradually acquires rich russet tones as autumn advances.
- Garden care: Incorporate lots of well-rotted garden compost into the planting hold. Leave flower heads to dry out through the winter, adding valuable texture to plantings. Apply a light mulch (3cm) of well-rotted garden compost after cutting back old foliage and before new growth emerges in spring.

Q:Hi I bought 3 of these plants and have had them over 5 years. I tend to cut them back in spring as I begin to see new shoots. I have not divided any of them. Every year they have become smaller and smaller and 2 of them have nearly died completly. I mulch well. What am I doing wrong? Is there anything I could to emcourage growth, as I'm thinking of buying some more - as they look lovely.Asked on 7/4/2015 by Black Lily from Catford
These plants love a reliable source of moisture, so it is important to make sure they do not dry out. Also, they like nutrient-rich soil, so make sure when you mulch, you use something like a composted organic manure.Answered on 8/4/2015 by Anonymous from crocus

Q:Salvia suggestion please
Please could you advise me? I am looking to use a Salvia to plant with Buxus balls, Hakonechloa and Lavender. I need a strong, long flowering and easy caring Salvia variety that will not grow too tall. Your advise would be invaluable Thank you JackieAsked on 8/26/2009 by jackie middleton
A:Hello Jackie, Salvia nemorosa Caradonna probably has the longest flowering period, but it does get to 75cm tall - just click on the following lin to go straight to it. http://www.crocus.co.uk/plants/_/perennials/salvia-nemorosa-caradonna/classid.2000006629/ If that is too tall, then Saliva nemorosa Ostfriesland may be a better option http://www.crocus.co.uk/plants/_/perennials/salvia-nemorosa-ostfriesland/classid.3545/ I hope this helps.
